Semi-functional scope?

About 2 years ago a friend of mine gave me a "Bell & Howell Schools" scope. I put it in my basement for a few years until I've had time to look at it. A friend guided me through the alignment over the phone so I get my dot centered on the screen. But I can't get it to start (is sweeping the word?) I just get the dot. Turning the controls to any place other than where he told me results in the dot falling off the screen (to the left usually). I've tried to get results by connecting low-level audio sources including music and white noise, but still nothing on the display other than the dot. Any ideas? I need to have it working by 3rd period Friday because my friend is bringing an Arp 2600 analogue synthesizer to my chemistry class to demonstrate different wave forms and it will be a lot more effective if we can demonstrate the different waves if theyc an be seen. Oh, I forgot to mention that when I opened it up, there was a REALLY long CRT (I'd say more than 1.5 feet) that ran the entire length of the cabinet. Other than a bit of a rusty shield under one of the went holes, it was REALLY clean on the inside... but had several spider webs and dead insects. How something can be home to little creatures but not get dusty is quite beyond me... the only openings are the vent holes in the top, which are long skinny things that shuold have let it all the dust...
